The butterfly semiconductor laser is the most commonly used long-distance transmission optical signal amplification device in the optical fiber communication industry, but the packaging cost of the butterfly semiconductor laser is always high, and the development speed of the optoelectronic device industry is greatly limited due to the huge contradiction between the expensive packaging cost, the low packaging efficiency and the increasing demand.
The biggest bottleneck in the packaging industry of optoelectronic devices is the packaging cost, and the key reason for limiting the cost is the degree of automation of packaging. In the automation process, the optical fiber coupling (optical fiber alignment) technology and the pigtail fixing technology need to be considered in an important way. In the optical fiber coupling process, the alignment mode is mostly that whether the optical fiber is aligned or not is judged manually according to the output power of the laser, and fine adjustment is carried out by using an adjusting platform.

Therefore, how to solve the problems of low optical fiber coupling precision, high packaging cost, low product yield and the like in the prior art is the central importance in the development of the butterfly-shaped semiconductor laser at present. During the packaging process, it is particularly important that accurate soldering is performed.
